Enter the actual weight (lbs) and the ideal weight (lbs) into the Excess Weight Calculator. The calculator will evaluate the Excess Weight. 

Excess Weight Formula

The following two example problems outline the steps and information needed to calculate the Excess Weight.

EW = AW - IW


  • EW is the Excess Weight (lbs)
  • AW is the actual weight (lbs) 
  • IW is the ideal weight (lbs) 

To calculate excess weight, subtract the ideal weight from the actual weight.

How to Calculate Excess Weight?

The following steps outline how to calculate the Excess Weight.

  1. First, determine the actual weight (lbs). 
  2. Next, determine the ideal weight (lbs). 
  3. Next, gather the formula from above = EW = AW – IW.
  4. Finally, calculate the Excess Weight.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

actual weight (lbs) = 200

ideal weight (lbs) = 150

EW = AW – IW = ?
